the Perfect Punishment (Glynda x Emerald) [Futa/Futa]

Emerald sat in the soft chair at Glynda's desk in the teacher's office at Beacon Academy. Drumming her fingers gently on the desk, she looked across the desk at the teacher herself.
"I trust you know why you're here."
The older woman said, giving a stern glance at her student.
"Because I've missed 3 classes in the last two weeks?"
Emerald asked.
Glynda nodded.
"Indeed. And these type of no-excuse absences will not be tolerated in my classes, do you understand."
"Yes ma'am."
Emerald replied, her voice soft. She had indeed been skipping the occasional class to get her rocks off, and apparently it hadn't gone unnoticed.
"Typically the punishment for something like this is two days of helping clean the classroom. But there is... another option."
Glancing down, Emerald saw a bulge forming in the front of the teachers pants.
"I have needs."
Glynda continued, a small smirk breaking her otherwise serious expression.
"And, instead of cleaning the classroom, you could choose to help me out."
Letting her pants drop to the floor, Glynda slapped her fully erect 6.4 inch member against the desk.
As much as Emerald didn't like getting taken advantage of, she'd certainly rather take the teacher's dick for a bit then spend several hours cleaning up a classroom.
"Alright. You can fuck me."
Emerald sighed, somewhat reluctantly.
"Smart choice."
Glynda said, walking around to stand behind Emerald.
As the dark-skinned girl felt the teacher pulling down her shorts she smirked.
"You know, for someone of your authority I thought you'd be a bit... bigger."
"Trust me girl,"
Glynda said, squeezing the soft, warm flesh of Emerald's as Emerald felt the woman's cock rubbing against her skin.
"I know how to fuck."
A few seconds later, Emerald let out a cry of pain and pleasure, gripping the edge of the desk tightly, as Glynda thrust into her unprepared asshole.
"Wr-wrong hole!"
Emerald groaned, gritting her teeth at the pain of the unexpected girth in her tightest hole.
"On the contrary,"
Glynda intoned, thrusting again and giving Emerald's ass a hard smack with one hand.
"I never said what hole id be fucking."
It had been a long time since the dark-skinned student had taken anything except a dildo in her ass, so each rhythmic thrust from the older woman sent waves of pain through her as she felt her ass being stretched out.
"Mmmmm... that's nice..."
Glynda said calmly.
"Nice and tight."
"I don't... fucking... do anal... ow!"
Emerald's words were cut off with a yelp of pain as she got a hard slap on the ass.
"Language."
Glynda scolded.
"And you really should. You're so good at taking it~"
Groaning as she felt 4 inches of cock shoved into her tightest hole, Emerald gripped the edge of the desk so tight her fingernails left marks. Through the fog of pain and pleasure that clouded her mind, she saw all of the other nail marks on the desk, realizing she was far from the first student to receive this kind of punishment.
Glynda was thoroughly enjoying herself as she set a more rhythmic pace. Of all the students shed fucked in this office over the years, the dark-skinned huntress in training was by far one of the tightest. She felt Emerald's ass tighten as she pushed deeper and deeper, now just over 5 inches inside.
Emerald was panting heavily, feeling her cock slap gently against her thigh and the inside of her shorts as Glynda's movements became harsher, the woman digging her nails gently into Emerald's ass. Reaching back slightly with one hand, Emerald began to massage one of her breasts through here top, until another had slap on the ass from the teacher made her cry out once again.
"Hands on the desk. This is your punishment, remember?"
"Y-yess m-ma'am."
Emerald groaned, feeling the older woman's balls begin to graze the skin of her ass with each thrust.
Glynda was 6.2 inches deep now and showed no signs whatsoever of stopping. With a massive effort, she thrust her cock base deep into Emerald, causing the dark-skinned student to groan loudly as Glynda set her new pace, thrusting balls deep each and every time.
The older woman gripped Emerald's ass tighter, now thrusting deep with all her might, her chest rising and falling more quickly as she breathed more heavily, feeling her orgasm brewing deep inside her.
"Almost over..."
She panted, leaning down to whisper in Emerald's ear, getting only a strained groan in return.
Glynda's orgasm hit her with full force. Hilting herself deep inside Emerald's tight ass, she gave a loud groan as she came, pumping several loads of warm, sticky spunk into the student's tightest hole.
When it was all over, Glynda stayed buried inside Emerald for a moment, enjoying the tight feeling of the girl's ass on her slowly softening cock before slowly pulling out.
"There..."
She gasped as she lay down on her back on the desk, closing her eyes as she caught her breath.
"Isn't that better than cleaning classrooms?"
"Y-yeah."
Emerald said, standing up, groaning softly as she felt the remainder of Glynda's cum flow out of her asshole, pooling on the floor.
"You're free to go."
Glynda said dismissal, gesturing towards the door that lead back out into the rest of the school, her eyes still closed in relaxed bliss, her now flaccid 4.8 inches on full display.
The teacher only opened her eyes when she felt Emerald's hands on her shoulders, pushing her roughly down against the desk.
"What do you thing you're doing?"
The older woman asked, more than a trace of annoyance in her voice.
"Returning the favor..."
Emerald said, smirking.
Raising her hand slightly from where she lay on her back, Glynda noticed that Emerald had removed her shorts and panties, revealing her wonderfully smooth legs and a flaccid 6.6 inch cock.
She's bigger soft than I am hard!
Glynda realized as Emerald took a step closer.
"Don't you dare..."
Glynda warned, watching as Emerald laid her flaccid cock next to Glynda's own. The size difference was obvious.
"I said don't you dare!"
Glynda said again, real sternness in her voice now.
"You're a combat instructor."
Emerald pointed out, removing one hand from the teacher's shoulders to stroke her dick.
"Come on, fight me off."
Glynda made a valiant effort to rise off the desk but found the force exerted by Emerald's hand to be too strong, holding her in place. All the woman could do was watch as the dark-skinned girl's cock slowly hardened, turning into a thick 9.5 inch beast of a dick.
Emerald grinned as she saw the look of shock on the teacher's face. Emerald had grown quite a bit since she first arrived at the academy, thanks in part to the dust training she had been doing with Neon.
With one deft move, Emerald gripped Glynda's body and flipped her over, forcing her to assume the same position she had made Emerald take, slumped over the desk with her ass and legs just off the edge, her cock dangling there as well.
"Such as nice juicy ass..."
Emerald explained, giving Glynda's butt a smack hard enough to make the woman wince.
"I bet you're used to taking big dicks huh?"
"No I'm not!" the older woman growled.
"Well, allow me to introduce you to a whole new experience."
Glynda roared in pain as the dark-skinned student thrust hard into her tight hole. Not only was Emerald's cock longer than her own, but considerably thicker as well.
"Keep it down would you?"
Emerald said, slapping the woman's ass as she gave a second thrust.
"G-go... easy..."
Glynda gasped, feeling her tight asshole stretching to accommodate the meaty girth of Emerald's dick.
"Not really an option with a tight ass like yours."
Emerald said, already 4 inches deep in the teacher's ass."
"You're squeezing the hell outta me~"
Slowly, she set her pace, slamming her hips forward over and over again, each thrust followed by a noise of mixed pleasure and pain from Glynda, her cock slapping against the inside of her thigh.
Emerald was used to fucking a nice tight ass now and then, Jaune and Cinder being two of her more recent conquests, but Glynda's was on a whole other level entirely. As the dark-skinned huntress-in-training forced her way deeper into the blonde-haired beauty, the woman's ass got tighter and tighter.
She really must not have any experience.
Emerald thought, slapping Glynda's ass hard and getting a rather pleasing yelp of surprise in return.
Despite her best intentions, Glynda was beginning to enjoy the treatment somewhat. The painful pleasure of Emerald's cock slamming into her had begun to arouse her greatly, and the blonde moaned softly as she felt her cock hardening once more.
Emerald smiled to herself as she noticed Glynda's body beginning to betray her, the teacher's dick already fully hard at 6.4 inches.
"Awww. Are you starting to enjoy it?"
Emerald cooed, squeezing Glynda's ass with both hands as she pounded the 7th inch of her dick into the woman.
"N-no... shut up..."
Glynda growled back. But her body was telling a different story.
After only a few minutes, the harsh, powerful thrust of Emerald's member became to much for the blonde to handle. Her orgasm was fast approaching.
"Ahhh-hahaahhh-haaahhhhhh~"
She groaned as, with a jolt, she came.
Jets of cum shot from Glynda's cock, splattering against the side of her desk as well as the stone floor of the office, drenching her own feet in the process.
"Its okay,"
Emerald said with a smirk.
"You don't have to say you love the feeling of having my perfect chocolate cock buried deep in your ass, I already know..."
She was well and truly in her element now, fully in control with a good pace, 8 inches deep inside her professor's asshole.
"Rule number one of trying to be an alpha, don't try to act so tough towards someone withe a bigger cock."
Emerald said, speeding up her motions slightly.
Glynda could only groan in reply as she came again, a second load of spunk splattering on the floor at her feet.
"Rule number two,"
Emerald continue, really pushing hard now,
"If you're gonna go the route of playing the devil, have the stuff to back it uo."
The dark-skinned blonde was base deep in glides ass now, her large balls slapping against Glynda's with every powerful thrust.
Glynda gripped the edge of the desk tightly, her fingernails leaving marks in the mahogany paintwork as she gritted her teeth, chumming for a third time. Wave after wave of pleasure rolled through her as she felt Emerald's thrust increase in speed, the girl's pace becoming faster and faster.
"Almost there..."
Emerald muttered, increasing the tightness of her grip on her teacher's ass as she's sped up,
"Just a little longer... haahhhhhhhh~"
She let out a loud sigh of satisfied pleasure as she came, unloading a weeks-worth of pent up cum into Glynda's tightest hole. And yet she wasn't done. Pulling out, she jerked her cock for several seconds, the final few spurts of cum coating the older woman's back.
"That's how you be an alpha."
She said, smirking as she got dressed.
Glynda sat up slowly, her whole body aching, watching as the dark-skinned student picked up her bag and headed for the door.
"Good luck walking right for the next week."
Emerald said, and just like that she was gone, back out into the hallways of Beacon, closing the door behind her.
